No. 379.] THE MAMMALS OF LABRADOR. 501 
Measurements. The type, young adult (probably ¢). Basilar 
length of Heusel, 205 ; occipito-nasal length, 187.4; zygomatic 
breadth, 129.6; mastoid breadth, 101.4; breadth between post- 
orbital processes, 72.6; inter-orbital breadth, 51.2; palatal 
length, 114.6; post-palatal length, 91 ; greatest length of single 
half of mandible, 164. 
Remarks. Mr. Sornborger brought back from Labrador three 
fine skulls of the Labrador black ‘bear: one from Hopedale, 
No. 7412, middle-aged adult (probably 3); one from Maine, a 
two-thirds grown young; and the type of the form from 
kak. i 
These three skulls show the black bear of the Labrador Pen- 
insula to be easily separable from that of the Canadian regions 
of eastern North America. It is to be regretted that no skins 
were procured, as the external characters remain unknown. 
The Labrador black bear is common throughout Labrador 
north to the tree limit. One would expect to find specimens 
from southwestern Labrador more nearly like true U. ameri- 
canus, if not that form itself.
